I’m building my first stick and I’m having some problems drilling clean holes for sunk-in/recessed buttons, using a hand drill with spade bits.
I first drill a 30mm hole a couple of milimeters deep in the surface (maple wood) then a 24mm with the same center as the previous hole, it works but the result is very dirty. The space between the two holes should be nice and flat so the button can rest on it but instead the wood is splintered, with fibers coming out.
I would like to obtain something clean like this:
What am I doing wrong, am I not using the correct drill bit or tool ?
Thanks in advance for any help
